I guess when it comes down to it, what I like about hosting my own email comes down to a matter of information and control; I like being able to look at the logs and being able to know the status of individual messages via the logs, and figuring out what new rules to make between the email headers and the logs. No email service I know of will offer you the email logs of your own messages. There are also interesting legal ramifications of having your email hosted by a 3rd party rather than on a privately owned or rented space; in the latter the data is considered personal property, and in the former it isn't. This is along the same lines as the reasoning Eben Moglen used in his proposal of the "Freedom Box" and why communications via Facebook and Twitter are likewise a problem. As such, I suggest having a look into the Stored Communications Act. https://ssd.eff.org/3rdparties/protect/email-inbox As long as you're careful to remove email that's > 180 days from your email provider you should be fine. -- Chris -- Chris Knadle [email protected] > On Sep 18, 2012 2:04 PM, "Chris Knadle" <[email protected]> wrote: > > On Tuesday, September 18, 2012 11:00:49 AM Sean Dague wrote: > > > On Tue, Sep 18, 2012 at 9:23 AM, Chris Knadle > > > <[email protected]>wrote: <snip> > > > > > > > Here are some statistics for my server for Sept 15 - 16 (these > > > > statistics > > > > > > are sent daily, via a Perl script that comes with the version of > > > > Exim4 > > > > in > > > > > > Debian): > > > > > > > > mail rejection reasons by message count > > > > --------------------------------------- > > > > > > > > Messages Mail rejection reason > > > > > > > > 516 Rejected HELO/EHLO: syntactically invalid argument > > > > 378 Listed at <DNSBL location 1> > > > > > > > > 97 Msg rejected due to spam score > > > > 22 Rejected EHLO: non-FQDN HELO greeting > > > > 12 Rejected EHLO: raw IP address used in HELO/EHLO greeting > > > > 10 Rejected RCPT: Unrouteable address > > > > > > > > 7 Rejected EHLO: forged localhost > > > > 4 No email address in To: field > > > > 3 Listed at <DNSBL location 2> > > > > 3 Rejected RCPT: Sender verify failed > > > > > > So, I think here is part of the difference.
